The embodiments herein relate to timing advance offset for uplink/downlink switching in New Radio (NR). In one embodiment, there proposes a method in a wireless communication device, comprising: determining a timing advance (TA) offset for uplink/downlink switching, wherein the TA offset is at least based on the time offset requirement for uplink/downlink switching in different scenarios used in communication between the wireless communication device and a network node; applying the determined TA offset in the uplink communication from the wireless communication device to the network node. With embodiments herein, uplink/downlink switching time for NR is defined.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The client application of claim 1, wherein the TA offset depends on whether the frequency range is a first frequency range or a second frequency range, wherein the first frequency range is a frequency range above 6 GHz and the second frequency range is a frequency range below 6 GHz.
3. The client application of claim 1, wherein the first TA offset value is different than the second TA offset value.
4. The client application of claim 3, wherein the frequency threshold is about 6 GHZ, the first TA offset is about 20 μs, and the second TA offset is about 10 μs.
8. The wireless communication device of claim 6, wherein the TA offset has a first TA offset value for a first frequency band that is below a frequency threshold for a time division duplex and a second TA offset value for a second frequency band that is equal to or above the frequency threshold, wherein the first TA offset value is greater than the second TA offset value.
10. The wireless communication device of claim 6, wherein for non-time division duplex, non-TDD, the TA offset is 0.
11. The wireless communication device of claim 6, wherein the first TA offset value is different than the second TA offset value.
13. The network node of claim 12, wherein the TA offset is sent in a random access response, (RAR) message.
14. The network node of claim 12, wherein the processing circuitry is further configured to send a timing advance corresponding to a propagation delay between the wireless communication device and the network node to the wireless communication device, in a TA command in a random access response (RAR) message.
15. The network node of claim 12, wherein the TA offset has a first TA offset value for a first frequency band that is below a frequency threshold for a time division duplex and a second TA offset value for a second frequency band that is equal to or above the frequency threshold, wherein the first TA offset value is greater than the second TA offset value.
18. The network node of claim 12, wherein the first TA offset value is different than the second TA offset value.
